This actually looks pretty solid. It's going to run exactly one time for each HTTP request times the total number of HTTP requests from all users over some given amount of time. That's not a bad thing. The order that you're placing these is marginally important for such a small iRule. For anything substantially larger, I'd recommend putting more prevalent conditions closer to the top.
